Frequently Asked Questions
Q: What is the SU 554-XL load wheel?
A: The SU 554-XL is a load wheel designed for electric lift trucks and material handling equipment. It is sold as a wheel only without hub or bearing assembly included. The XL designation indicates extra-large or extended-wear formulation for heavy duty service. Exact diameter and width specifications are available in your product data sheet.
Q: Is the SU 554-XL compatible with my current truck wheels?
A: Compatibility depends on your equipment model and bore size. Verify your truck documentation lists SU 554-XL as an approved replacement part. If you are unsure, provide your truck model number and serial range to confirm fitment before ordering. Wheels must match in diameter and width across all positions on your equipment.
Q: What makes the XL designation different from standard load wheels?
A: XL wheels are engineered from premium polyurethane formulations designed for maximum load capacity and extended wear life in demanding heavy-duty applications. They resist wear, impact damage, and floor contaminants better than standard wheels. XL wheels typically deliver 30-50% longer service life and higher load ratings.
Q: Do I need to transfer my existing hub assembly to the SU 554-XL?
A: Yes. The SU 554-XL is a wheel only. You must remove the wheel from your old assembly and transfer the hub, bearings, and all mounting hardware to the SU 554-XL. If your current hub is damaged or worn, repair or replace it before installing the SU 554-XL. If you prefer an assembled unit, order the SU 554-XL-A instead.
Q: What symptoms indicate the SU 554-XL wheel needs replacement?
A: Replace the SU 554-XL if you observe flat spots or divots on the running surface, visible cracks or chunks missing from the wheel, uneven wear patterns, a diameter worn below specifications, excessive vibration or wobbling, or reduced traction causing slipping. XL wheels typically last 3-5 years under normal conditions, longer with regular maintenance.
Q: Can I mix SU 554-XL wheels with standard load wheels on the same truck?
A: No. Always use matching wheels across all positions on your equipment. Mixing wheel types or sizes creates uneven weight distribution, causes steering and tracking problems, and creates a safety hazard. If you upgrade to SU 554-XL, replace all wheels on the truck at the same time.
